Huntington, Samuel P. "Political Development and the Decline of the American System of World Order." Daedalus  v. 96, n. 3 (1967): 927-929.

“By the year 2000 it should be clear retrospectively that the dominant feature of international politics during the thirty years after WWII was neither the East-West confrontation between the U.S. and the Sino-Soviet bloc nor the North-South conflict between the developed and the undeveloped countries. Instead, the crucial relationship was that between the United States and Western Europe, and the dominant feature of international politics during this period was the expansion of the power of the United States.”
